Effects of Exposure to an Entertainment-Based Genetic Testing Narrative on Genetic Testing Knowledge, Attitudes and Counseling Discussion Intentions.

This study explores the effects of exposure to a reality television narrative depicting genetic testing on attitudes and intentions, looking particularly at the effects of narratives containing elements of misinformation on genetics-related knowledge accuracy. In an experiment, participants completed a baseline survey, viewed a high versus low-accuracy narrative, then completed a follow-up survey. Exposure to a low-accuracy narrative was associated with lower knowledge accuracy. Indirect effects of identification and transportation on intentions to talk to a doctor about genetic testing also were detected via attitudes and reduced message counterarguing. Results illustrate the negative implications of inaccurate narratives on knowledge, which is concerning given the public's low level of genetic literacy, as well as the critical role narrative engagement may play in shaping public attitudes and intentions regarding genetic testing.
